The module, which aims to increase the students' awareness of their own expressive means and to improve their discourse analytical skills, has two parts. Part A, which takes place in the first semester, it taught by S. Bernardini with the support of G. Aragrande. This part covers the theoretical and methodological bases of corpus linguistics and mediated varieties of English, and provides practical experience of corpus use for academic writing tasks. Part B, taught by A. Partington in the second semester, applies and extends the competences acquired in part A, applying them to corpus-aided discourse analysis of selected text types.
